Hi All, I try run rolling upgrade with subject versions. And it fails with the very strange message. I added the image with current state and in ambari-server.log I see this lines: WARN [Server Action Executor Worker 2015] ServerActionExecutor:471 - Task #2015 failed to complete execution due to thrown exception: java.lang.NullPointerException:null java.lang.NullPointerException at org.apache.ambari.server.serveraction.upgrades.ConfigureAction.execute(ConfigureAction.java:200) at org.apache.ambari.server.serveraction.ServerActionExecutor$Worker.execute(ServerActionExecutor.java:550) at org.apache.ambari.server.serveraction.ServerActionExecutor$Worker.run(ServerActionExecutor.java:466) at java.lang.Thread.run(Thread.java:745) Please help.

Hi All, I tried upgrading from HDF 3.1.1.0 to HDF 3.1.2. I upgraded to the new version of Ambari 2.6.2 from Ambari 2.6.0 And now Ambari not work as needed. In upper menu do not exist, all menu items as " Dashboard Services Hosts Alerts Admin" not there. If I click on specific service and press on button "Service Actions" only start and stop there and circle which show the loading process. And I can to continue upgrade process because Ambari asks to run a service check. If I install the new version of HDF 3.1.2 (not upgrade) all work as needed. Please help. In logs of Ambari I cannot find anything strange. Update: I found some strange rows in ambari-server.log Maybe something in scheduler?

Hi All, We set jmxremote and saw what NiFi has a memory leak. GC can not clean located memory, and after 2-3 days NiFi starts to work strange(all the time tries switch primary, monitoring API does not answer). We made the update of HDF from 3.0 to 3.1. Our environment is production, therefore we are limited for actions. In our flow, we use all standard processors and one ExecuteScript (ECMAScript) Java8 If you know how to search leak source or have any idea how to search we will be grateful. Thanks, Ilya ...

Hello All, I asked previously about PutSQL behavior on the node or network failure.Here But now I have the more complicated issue. How with NiFi and PutSQL processor I can guarantee "exactly one" policy? Which flow do I need to build? Thanks, Ilya ... View more

Hi All, I have the theoretical question. What happened if PutSQL sent the request to SQL server and exactly in this time Node failed(die/power shutdown). PutSQL did not receive the answer from the SQL server if rows were inserted or not. What does happen in this way? Will this rows be sent one more time? or will be sent to fail connection? Or something else will happen? Thanks ... View more
